Inspection Method for Sensor Connectors or Wires

1. Connect the WDS or equivalent to the DLC-2.
2. Turn ignition switch to ON position (Engine OFF).
   NOTE:

   • If engine starts and runs, perform the following steps at idle.
3. Access PIDs for the switch you are inspecting.
4. Shake each connector or wire harness a little vertically and horizontally while monitoring the PID.
   • If PID value is unstable, check for poor connection.
